Definitions
- This invention relates to an internal combustion engine and particularly to a direct injected internal combustion engine provided with a supercharger.
- the direct injector As the performance of the engine is improved, however, it may be difficult for the direct injector to supply not only the minute quantities of fuel required under very low speed, low load conditions as well as the larger quantity of fuel necessary to obtain maximum power output. Although this can be done by providing injectors that have a higher capacity, then the ability to inject controlled small amounts of fuel under low load conditions becomes very difficult. Also, if the injection is set so as to provide adequate and carefully controlled small amounts of fuel, then fuel must be injected for a longer time period under high speed and high load conditions and this can result in unwanted exhaust gas constituents because of the fact that the fuel may not have had the time to vaporize before combustion starts.
- An internal combustion engine constructed in accordance with an embodiment of the invention is provided with a pair of relatively moveable components that define a combustion chamber, the volume of which varies cyclically during the engine operation.
- An induction system is provided for delivering an air charge to the combustion chamber.
- a first fuel injector is provided that injects fuel directly into the combustion chamber.
- a second fuel injector is provided for injecting fuel into an induction system that supplies an air charge to the combustion chamber.
- a control selectively controls the timing and duration of fuel injection from both of the fuel injectors.
- the engine is provided with a supercharger which is mounted upstream of the second fuel injector.
- FIG. 1 is a cross sectional view taken through a single cylinder of an internal combustion engine constructed in accordance with an embodiment of the invention and showing the piston thereof at top dead center position in solid lines and at bottom dead center position in phantom lines.
- FIG. 2 is an enlarged cross sectional view, in part similar to FIG. 1, and shows primarily the upper end of the cylinder block and the cylinder head assembly.
- FIG. 3 is a graphical view showing the various ranges of engine speed, engine torque and the control arrangement and strategy in connection with the fuel injectors.
- an internal combustion engine constructed and operated in accordance with an embodiment of the invention is identified generally by the reference numeral 11 .
- the engine 11 is shown only by reference to a cross section through a single cylinder of the engine 11 and specifically taken along the axis of a cylinder bore 12 formed in a cylinder block 13 of the engine.
- the invention is described in conjunction with only a single cylinder, it should be readily apparent to those skilled in the art how the invention may be employed with engines having various cylinder numbers and cylinder configurations.
- the cylinder bore 12 is closed at its upper end by a cylinder head assembly 14 that is affixed to the cylinder block 13 in a known manner.
- the undersurface of the cylinder head assembly 14 is provided with one or more recesses 15 depending upon the number of cylinder bores 12 . These recesses 15 cooperate with the cylinder bores 12 and the heads of pistons 16 that reciprocate therein to form the combustion chambers of the engine 11 .
- the cylinder head recess 15 forms the primary portion of the combustion chamber at top dead center and at times the reference numeral 15 will be referred to as the “combustion chamber”.
- the piston 16 is connected by a piston pin 17 to the small end of a connecting rod 18 .
- the big end of the connecting rod 18 is journalled on a respective throw 19 of a crankshaft 21 .
- the crankshaft 21 is rotatably journalled within a crankcase assembly that is formed by a skirt 22 of the cylinder block 13 , a bearing cap member 23 and an oil pan 24 , all of which are connected to each other in a suitable manner.
- the actual form of journaling for the crankshaft 21 can be of any desired type.
- an induction system indicated generally by the reference numeral 25 is provided for delivering an intake air charge to the combustion chambers 15 .
- the induction system 25 includes a supercharger 26 , which is, in the preferred embodiment, a turbocharger.
- This supercharger 26 is provided with an inlet 27 that draws atmospheric air through a suitable air filter and silencing arrangement. The supercharged air is then discharged through a supply conduit 28 to a throttle body 29 in which a flow controlling throttle valve 31 is provided.
- the throttle body 29 Downstream of the throttle valve 31 , the throttle body 29 cooperates with an inlet 32 of a plenum chamber 33 which extends generally longitudinally of the engine above the cylinder head assembly 14 .
- Intake manifold runners 34 extend from the plenum chamber 33 to cylinder head intake passages 35 , each of which communicate with a respective one of the cylinder head combustion chamber 15 through an intake valve 36 . It will be seen that the manifold runners 34 have curved portions 37 that terminate in straight sections 38 which cooperate with the generally straight cylinder head intake passages 35 so as to provide a direct and unobstructed airflow into the combustion chamber 15 .
- the intake valves 36 cooperate with valve seats 39 formed in the cylinder head recesses 15 in an appropriate manner.
- the intake valves 36 are opened and closed by an intake camshaft 41 that is journalled in the cylinder head assembly 14 in a known manner, as will be described later, and which is contained within a cam cover 42 that is detachably affixed to the cylinder head assembly 14 .
- a first series of fuel injectors of the direct injection type one of which appears in the drawings and is indicated by the reference numeral 43 , are fixed in the cylinder head assembly 14 and have their discharge nozzles communicating with the combustion chamber 15 at one peripheral edge thereof.
- the fuel injectors 43 are supplied with fuel from a suitable fuel source and are controlled in a manner, which will be described hereinafter.
- a second series of fuel injectors of the manifold type are mounted in the curved portions 37 of the intake manifold runners 34 .
- a spray axis 45 of each of these second fuel injectors 44 is aligned with a flow axis 46 of the straight portion 38 of the intake passage formed by the runners 34 and the cylinder head intake passages 35 .
- the fuel sprayed by the injectors 44 will be well mixed with the intake air and will not tend to impinge upon the walls of the intake passage.
- Spark plugs 47 are mounted in the cylinder head assembly 14 and are disposed generally on the axis of the cylinder bores 12 . These spark plugs 47 are fired by a suitable ignition system.
- Exhaust passages 48 are formed in the cylinder head assembly 14 on the side opposite the intake passages 35 . These exhaust passages terminate in openings that communicate with the turbine phase of the supercharger 26 through a suitable manifold arrangement 49 . From the turbine of the supercharger 26 the exhaust gases exit through a flange 51 , which communicates with a suitable, exhaust system.
- Exhaust valves 52 are provided at the cylinder head recess surface end of the cylinder head exhaust passages 48 . These exhaust valves 52 are operated by an exhaust camshaft 53 , which is driven in a suitable manner along with the intake camshaft 41 . Specifically, the intake and exhaust valves 36 and 52 are operated by respective lobes 54 and 55 (FIG. 2) of the intake and exhaust camshafts 41 and 53 , which act upon thimble tappets 56 and 57 , respectively, supported for reciprocation in the cylinder head assembly 14 . These act against coil compression springs 58 and 59 , respectively, which urge the valves 36 and 52 toward their closed positions within valve guides 61 and 62 formed in the cylinder head that support the stems of the intake and exhaust valves 36 and 52 , respectively.
- FIG. 3 there is a curve, indicated by the reference character B which delineates the range when only the fuel injector 43 is employed from the range when both injectors 43 and 44 are employed to supply fuel.
- the curve A under which the engine operates in a stratified charge mode. This area is indicated by the reference character S 1 .
- the injector 43 only injects a small amount of fuel necessary to sustain engine operation. This fuel is injected toward the gap of the spark plug 47 and at a timing to insure that the charge will ignite even though the total charge in the combustion chamber 15 is less that stoichiometric.
